I used the essential mod to play with friends a couple of months ago and I just loaded up a world backup from 1.20.1 so that I could use the Create mod, and when the world finished loading I didn't have my own inventory, I had my friends', meaning that the player data has gotten mixed up and if he was to log onto the server he would likely have my gear since I have his. If anyone can help me I would greatly appreciate it because my friend has no plans on getting back on the world he moved on from it ages ago. I need to make it so the game assigns the right player data file to my account.

The Essential mod is completely incompatible with all of our modpacks, and there's no reason to use it. All of our modpacks already come with built-in, free world hosting, by clicking the "Share World' button in the Open to LAN menu. You can learn more by typing !ws in the #bots channel. You can also run type !server in the same channel to learn how to properly host a server for better performance and more flexibility. In modpacks that aren't owned by us, you can use mods such as e4mc or WorldHost to host a server completely for free without Essential's many issues and crashes and the microtransactions that they constantly bother users with. To learn more about alternatives to the Essential mod, check out this website.

you can check the playerdata folder but you might be cooked because essential frequently corrupts worlds
